The new BLEND command in AutoCAD 2012 creates a tangent spline in between two entities. This can save you a lot of time compared to manually working the Spline command. You can pick lines, arcs, open splines/polylines, or elliptical arcs. After you pick the first entity, and hover the cursor over the second one, a preview of the new spline will be shown.
Before you select the first entity, one option is CONtinuity. Type in CON and then you can select from Tangent or Smooth. Tangent will create a degree 3 spline with tangency continuity to the selected objects at their endpoints. Smooth will create a 5 degree spline with curvature continuity to the selected objects at their endpoints.
As expected, the new spline entity will be created using the current properties (layer, color, etc). Are you already using this? Is this new to you? No need for it? Leave a comment with your thoughts.
